CAR-AXLE Box.

SPECIFICATION forming part of Letters Patent No. 347,599, dated August 17, 1886.

Application filed March 23, 1886.

T0 all whom it may concern:

Be it known that I, ANToiNn C. HBERT, of Chicago, county of Cook, and State of Illinois, have invented certain new and useful 11nprovements in a Car-Axle Box, of which the following is a full, clear, and exact deseription,that will enable others to make and to use the same, reference being had to the accompanying drawings, which form a part of this specification.

This invention relates to iinproven'ients in that class of axle boxes or journal-bearings that are more particularly intended for use on street-cars; and the saule consists in certain tion, and arrangement ofthe several parts, as will be hereinafter set forth in detail.

Figure 1 is a view in perspective; Fig. 2, a vertical longitudinal section of the box proper in the plane 2; Fig. 4, the axle and frictionroller, being shown in full. Fig. 3 is a vertical transverse section in the angular plane 3 3, Fig. 2; Fig. 4, a vertical transverse section in the angular plane44, Fig. 2, looking in the direction indicated by the arrows. Fig. 5 is a perspective of the inside or back bearingbrass; and Fig. 6, a transverse section of the saine in the plane 6, Fig. 5, showing the brass provided with a bearing-surface of phosphorbronze.

' Referring to the drawings, A represents the upper p'art of the journal-box, A the lower part, and B the axle.

The back bearing-brass, C, is of the form shown in Fig. 5, and Ybears against the axle on the two sides, as shown in Figs. 3 and 4. The bearing-surface proper of this brass, having frictional contact with the axle, consists ofa piece of phosphor-bronze, a, let into the brass in the manner shown in Fig. 6. This provides a bearing-surface of great durability, and greatly lessens the cost of repairs. The front brass, C', will be constructed inthe saine manner, and is of the form shown in Fig. 2.

The loose single friction-roller D is located in the cavity a in the upper part of the box, and between the journal-brasses C C', as shown Ain Fig. 2. This roller is provided with a journal-bearing in the upper closed ends of the brasses, and just a little play is left between Serial No. 196,218. (No model.)

the ends of the journal-shaft a'zand the brasses, so as to provide for a slight lateral adjust*- ment or movement of the friction-roller and prevent these parts from binding or crainp- L ing. The roller D rests upon and has frictional contact with the upper side of the axle, thus providing a rolling bearing for said axle and greatly lessening the friction in the journal-box.

The friction-roller bearings are lubricated through the tubes a a, which con'ununicate with the oilpockets a5 in the top of the box. These oil-tubes pass down through perforations a in the bearing-biasses, the lubricant from the pockets dripping into the oil-chamber b underneath the axle, as shown in Figs. 2, 3, and 4.

E is a seinieircular metallic plate supported on the springs b b2,- and b b" are two layers of felt or similar material interposed between said plate and the under side of the axle, said springs serving to keep the felt up to a close bearing against the axle, so as to keep the saine in a constant state of lubrication. The oil is supplied to the layers of felt by capillary attraction through the medium of the wicking b5, leading up from the bottoni of the oil-chamber.

F is a dust-guard consisting of a rectangular piece of leather fitting into the recess d, (see Fig. 2,) and is provided with a circular opening for the passage of the axle, and fitting close to the same, so as to prevent dust and dirt from entering the journal-box. The upper part of the inner end of the box is provided with the hood-like projection d', which prevents dirt or mud from lodging on the axle close to the journal-box. cured to and supported in proper relation to the car by means of a suitable pedestal. This construction provides a journal-box that greatly reduces the friction of the rolling parts, is strong and durable, is easy of access for repairs, andthe frictional surfaces are constantly lubricated.

Having thus described iny invention, what I claim, and desire to secure by Letters Patent, is-

1. In an axle-box, the combination, with the upper part of said box, provided with oilpeekets, of a friction roller, the bearing- The box will be se- ICO the journal-box, Containing nu 0il-el1ambe1'", :md the means described for lubricating said 1o axle from the under side7 substantially as seb forth.
